HIV infection can usually be detected when symptoms appear.
There are three stages of HIV, the acute stage, the asymptomatic stage and the AIDS stage. Symptoms usually appear in the acute stage and the AIDS stage, and HIV antibodies can be detected.
Antibody testing for HIV requires two rounds of tests, a primary screening test and a confirmatory test. If both tests are positive, it indicates a high likelihood of HIV infection. Nucleic acid testing is the gold standard, and you will also need to go to the CDC for nucleic acid testing to confirm the diagnosis.
When suffering from AIDS, you should cooperate with your doctor in time for antiviral drug treatment, such as tenofovir, lamivudine, etc. Meanwhile, keep your mood happy, do some exercise appropriately, and develop good living habits and dietary habits in order to strengthen your immunity.
